H A Dng_pppoe.cdiff 154862 Thu Jan 26 11:06:49 MST 2006 glebius From the RFC2516 it is not clear, what is the correct behavior for a
PPPoE AC, servicing a specific Service-Name, when client sends a PADI
with an empty Service-Name. Should it reply with all available service
names or should it be silent? Our implementation had chosen the latter,
while some other had chosen the former (they say Linux and Cisco). Now
some PPPoE clients appear, that rely on the assumption that AC will
send all names in a PADO reply to a PADI with wildcard Service-Name.
These clients can't connect to FreeBSD AC.

I have requested comments from authors of RFC2516 via email, but
received no reply.

This change makes FreeBSD AC compatible with D-Link DI-614+ and
D-Link DI-624+ SOHO routers, and probably others.

Big thanks to D-Link's Russian office, namely Victor Platov, for
assistance and support in investigation and testing of this change.

Details:
o Split pppoe_match_svc() into three different functions serving
different purposes:
- pppoe_match_svc() - match non-empty Service-Name tag from PADI
against all available hooks in listening state.
- pppoe_find_svc() - check that given Service-Name is not yet
registered.
- pppoe_broadcast_padi() - send a copy of PADI packet with empty
Service-Name tag to all listening hooks.
o For NGM_PPPOE_LISTEN message use pppoe_find_svc().
o In ng_pppoe_rcvdata() in a PADI case use pppoe_match_svc() for
a non-empty Service-Name tag, and pppoe_broadcast_padi() in
either case.

A side effect from the above changes is that now pppoed(8) and mpd
will reply to a empty Service-Name PADI sending a PADO with two
Service-Name tags - an empty one and correct one. This is not fatal,
and will be corrected in pppoed(8) and mpd later. No need to update
node interface version.
